Bats too

- "Tests were used to determine how much napalm an individual bat could carry, determining that a 14 g (0.5 oz) bat could carry a payload of 15–18 g (0.53–0.63 oz)..."

Similar ideas were (perhaps apocryphally) used in the medieval ages,

- "Olga then instructed her army to attach a piece of sulphur bound with small pieces of cloth to each bird. At nightfall, Olga told her soldiers to set the pieces aflame and release the birds. They returned to their nests within the city, which subsequently set the city ablaze. As the Primary Chronicle tells it: "There was not a house that was not consumed, and it was impossible to extinguish the flames, because all the houses caught fire at once."[22]"

Birds, bombs, fire, and vengeful Kievans as well:
